The Dancing With the Stars cast is changing things up once again, and ET happily tagged along.

For Monday's episode, the six remaining teams will pair off to perform side-by-side routines inspired by various stage shows they traveled around the country to see.

"This is the first time we've ever done a challenge like this on the show," Alexa PenaVega's pro dance partner Mark Ballas said.

The pairing works as follows. Bindi Irwin with Derek Hough and Alexa with Mark will face off in a Chicago duet dance inspired by the show on Broadway, while Nick Carter with Sharna Burgess and Tamar Braxton with Val Chmerkovskiy will perform dueling rumbas in a routine influenced by "The Beatles Love" Cirque Du Soleil show at The Mirage Las Vegas. Carlos PenaVega with Witney Carson and Alek Skarlatos with Lindsay Arnold will battle to the tune of "We Will Rock You" after catching a tribute show to Queen on the Royal Caribbean Cruise ship Anthem of the Seas.

As the season gets closer to the finale, confidence seems to be at an all-time high among the final six teams.

"We have the Beatles on our side," Val boasted to ET.

"You can't lose after that," Tamar chimed in.

And while competition is fierce, Carlos and Witney left room open to take advantage of the fun activities on their cruise, like surfing and riding in bumper cars.

"We haven't really rehearsed much, which is freaky," Carlos said. "But hey, we're having a good time."

Dancing With the Stars airs Mondays at 8 p.m. ET/PT on ABC.
